Counting with whole numbers
Counting with whole numbers
In Grade 3 you learnt how to count with whole numbers. Do you still remember how to count in 2s?
Let’s revise counting in 2s.
When you count in 2s, always add 2 to the previous number to get the next number.
+ 2 + 2 + 2 + 2 + 2
2 4 6 8 10 12
You can start with any number.
Study the numbers. Do you see that you can start at any number and count in whole numbers?
+ 2 + 2 + 2 + 2 + 2
63 65 67 69 71 73
In the above examples, you counted on or forwards. Using whole numbers, you can also count back or backwards.
Study the following numbers and complete the missing numbers.
Count back in 3s.
– 3 – 3 – 3 – 3 – 3 – 3 – 3
53 50 47 41 38 32
Now that your memory has been refreshed, you can apply what you have learnt.
